STEAM-RADIATOR.

Application filed April 2, 1914-..

To all whom t may concern Be it known that l, Jnssr. l?. WILLIAMS, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful improvements in Steam-Radiators; and do declare the following to be a f ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements 1n steam radiators and analogous forms of vapor heating systems employing flow and return pipes. n

The primary object of the invention 1s to provide extremely simple and efficient means whereby any air within the system may be freed. j

ln carrying out the above end in c0nnec tion with a radiator', l provide a transverse partition which obstruets communication between a portion of the flow and return pipes and a water trap which establishes communication between the two, the trap serv ing to allow water of condensation to return to the boiler and preventing any air from returning with said water. For the purpose of allowing this air to escape, I provide the return pipe with a vent adjacent the partition.

A secondary object of the invention is to construct portions of the radiator in such a manner as to provide an air pocket from which the vent discharges and to so position the partition as to cause it to most successfully perform its functions.

liith the above and other minor objects in view, the invention resides in certain novel features of construction and combination of parts hereinafter more fully described and claimed and shown in the drawings wherein Figure l is a vertical longitudinal section 'through the center of my improved radiator; F ig. 2 is an end view thereof; and Fig, 3 is a detail horizontal section taken upon the line 3-3 of F ig. l.

ln the accompanying drawings, I have illustrated a radiator comprising Lipper and lower longitudinal tubes l and 2, a number of upright tubes 3 establishing communication between the tubes l and 2 and entering the sides of said last mentioned tubes as is usual with devices of this character. The lower tube 2 is provided at one end with a Specication of Letters Patent.

combined steam inlet and outlet i with which the feed and return pipes, from the boiler to the radiator, may be connected in any suitable manner.

The lower side of the tube 2, adj acent the inlet 4l, is provided with a downwardly bulged portion 5 which constitutes a continnation of the endmost tubes 3 at this end of the radiator. rihis downwardly bulged portion constitutes a water trap as will be here inafter more clearly set forth. Extending across the water trap 5 and joined to the tube 2 and to portions of the tubes 3, at its edges, is a transverse partition 6 which is spaced from the lower end of the trap 5 and which is so disposed as to obstruct com' munication from the upper portion of the tube 2 and the interior of the upright tubes 3. The tube 2 is further provided, inside of the partition G, with an upwardly bulged portion 7 which constitutes an air pocket, said air pocket having an upright discharge opening or vent 8 which communicates with the interior of a discharge pipe 9, the latter having its inner end bent downwardly and engaged with the enlarged outer end of the vent 8 while its outer end extends upwardly. l/Vhen the parts are properly arranged, the pipe 9 extends longitudinally between the endmost tubes 3 and has its upwardly ex tending portion spaced a suitable distance from this end of the radiator.

The operation of the invention is as follows: Steam under pressure, is admitted through the nipple 4 and rises through the tubes 3 into the longitudinal tube l from which it gradually descends through the various tubes 3, as it cools and discharges into the return tube 2 at the bottom of the radiator. The air in the radiator, being heavier than the steam, will drop through the various tubes 3 and enter the tube 2, the returning steam forcing the air into the pocket 7 from which itis discharged through the vent 8 and pipe 9. As the steam cools, the water of condensation flows into the trap 5 and forms a liquid seal which prevents any air from returning through the nipple 4e. As the level of water within the tube 2 rises, the water within the trap 5 will of course likewise rise thus discharging thro-ugh the nipple 4 and returning to the boiler in a well known manner. lf the steam pressure employed is greater than the atmospheric pressure, the air from the interior of the radiator will be freely forced through the vent 8 and thus discharged. If however, the steam employed in the system, is below the normal atmospheric pressure, it becomes necessary to connect the outer ends of the pipes 9, on the various radiators, with a vacuum system, the operation of these systems being too well understood to require a more extended explanation.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have produced an eX- tremely simple radiator yet one which will be highly eiicient in operation and which will eliectually discharge any air from its interior thereby causing the steam to exert its greatest amount of energy.

Although in the foregoing description I have described certain elements as best adapted to perform the functions set forth., nevertheless, it is to be understood that various minor changes as to form, material, etc., may be resorted to within the scope of the appended claim without departing from or sacrificing any of the principles of this invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A trap for a radiator comprising a hori- Zontal tube, the lower surface 'thereof adjacent one end being transversely dished to produce a relatively wide cup-shaped liquid receptacle, a partition U-shaped in horizontal section integrally formed with and depending from the upper surface of said horizontal tube and having its lower end projecting into the dished portion of said tube and spaced from the bottom thereof, whereby said tube is divided into two compart ments, the flanges of said partition forming substantially, continuations of side walls of the narrow portion of said tube, one of said compartlnents having therein a combined steam and water inlet, said inlet opening into said compartment at a point immelf3 diately above the liquid level of the dished portion of said tube, the other compartment of said tube having therein a plurality of steam inlets, said last referred to compartment of said tube also having its upper surface formed with an opening, a flange surrounding said opening and forming a seat, and an air vent having one end disposed in said seat substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit* nesses.
